137680 ÷ 66 
We want to figure out the number of times 137680 can be divided by 66.

Step 1:
1 divided by 66 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 66

Advancing to step 2:
13 divided by 66 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 66

Going ahead to step 3:
66 can be fit into 137 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 132 from 137.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 66

On to step 4:
66 goes into 56 0 times with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 56 to get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 66

Advancing to step 5:
66 can be fit into 568 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 208.0
Subtracting 528 from 568 leaves us with 40.
Grab the next digit (0) from the dividend, add it to 40, then carry on: 400 / 66

Step 6:
If we divide 400 by 66, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2086.0
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 66, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2086.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
66 goes into 400 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2086.06
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 66, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 2086.06
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
66 goes into 400 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2086.0606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
66 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2086.0606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
66 can be fit into 400 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 2086.060606
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
40 divided by 66 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2086.060606
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
When dividing 400 by 66, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2086.06060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 2086.06060606 with a remainder of 4e-09.
